TL;DR: In this article, a flow type of apparatus is built to give equilibrium gas and liquid samples at elevated pressures and temperatures while minimizing thermal decomposition, and Saturated vapor and liquid compositions and K values are determined with this apparatus for the binary system hydrogen/tetralin (1,2,3,4-tetrahydronaphthalene) at four temperatures from 189.6° to 389.1°C, and seven pressures from 20 to 250 atm.
Abstract: A flow type of apparatus is built to give equilibrium gas and liquid samples at elevated pressures and temperatures while minimizing thermal decomposition. Saturated vapor and liquid compositions and K values are determined with this apparatus for the binary system hydrogen/tetralin (1,2,3,4-tetrahydronaphthalene) at four temperatures from 189.6° to 389.1°C, and seven pressures from 20 to 250 atm. Vapor pressures of tetralin are determined with the same apparatus, and values are reported at the four temperatures of this work.

TL;DR: In this paper, the critical constants and acentric factor are generally required in thermodynamic calculations based on the principle of corresponding states, and these properties of hydrocarbons and derivatives are correlated with the molecular weight, specific gravity, and normal boiling point.
Abstract: The critical constants and acentric factor are generally required in thermodynamic calculations based on the principle of corresponding states. In this work, these properties of hydrocarbons and derivatives are correlated with the molecular weight, specific gravity, and normal boiling point. Properties of n-alkanes are correlated with the molecular weight. Properties of other hydrocarbons and derivatives are expressed as perturbations from those of the n-alkanes, and the perturbations are corrlated in terms of specific gravity and normal boiling point.

TL;DR: In this paper, a correlation was developed for the solubility of hydrogen in hydrocarbon solvents at temperatures from 310 to 700 K and pressures to 30 MPa (300 bar).
Abstract: A correlation is developed for the solubility of hydrogen in hydrocarbon solvents at temperatures from 310 to 700 K and pressures to 30 MPa (300 bar). The fugacity of dissolved hydrogen at zero pressure is correlated as a function of solubility parameter and temperature. The high-pressure fugacity is obtained upon applying a Poynting factor for which the required partial molal volume of hydrogen is also correlated in terms of solubility parameter and temperature. The Henry constant of hydrogen is included in the correlation. The correlated results are compared with experimental data for 22 systems of binary and ternary solutions and five narrow-boiling cuts of coal liquids. The overall average absolute deviation for all systems studied is approximately 6%.

TL;DR: In this paper, the mutual solubilities at the three-phase vapor-liquid-liquid equilibrium pressure were experimentally determined for the binary mixtures of water with m-cresol, quinoline, indoline, 1,2,3,4-tetrahydroquinoline (THQ), thianaphthene, or 9,10-dihydrophenanthrene at temperatures from 293 to 502 K.
Abstract: Mutual solubilities at the three-phase vapor-liquid-liquid equilibrium pressure were experimentally determined for the binary mixtures of water with m-cresol, quinoline, indoline, 1,2,3,4-tetrahydroquinoline (THQ), thianaphthene, or 9,10-dihydrophenanthrene at temperatures from 293 to 502 K. The equilibrium compositions of both liquid phases, temperature, and three-phase equilibrium pressure are reported.

TL;DR: In this article, an equation of state (EoS) suitable for describing associating fluids is presented, which combines the simplicity of the Soave−Redlich−Kwong equation for the physical part and the theoretical background of the perturbation theory employed for the chemical part.
Abstract: An equation of state (EoS) suitable for describing associating fluids is presented. The equation combines the simplicity of a cubic equation of state (the Soave−Redlich−Kwong), which is used for the physical part and the theoretical background of the perturbation theory employed for the chemical (or association) part. The resulting EoS (Cubic Plus Association) is not cubic with respect to volume and contains five pure compound parameters which are determined using vapor pressures and saturated liquid densities. Excellent correlations of both vapor pressures and saturated liquid volumes are obtained for primary-alcohols (from methanol up to 1-tridecanol), phenol, tert-butyl alcohol, triethylene glycol, and water. Moreover, excellent prediction of saturated liquid volumes may be obtained from parameters which have been estimated by regressing only vapor pressures. Finally, we suggest a method for reducing the number of adjustable parameters for alcohols to three while maintaining the good correlation of vap...

TL;DR: In this article, a review of relevant experimental observations and modeling of high-pressure trickle-bed reactors, based on recent studies, is presented, and the effects of high pressure operation, which is of industrial relevance, on physicochemical and fluid dynamic parameters are discussed.
Abstract: A concise review of relevant experimental observations and modeling of high-pressure trickle-bed reactors, based on recent studies, is presented. The following topics are considered: flow regime transitions, pressure drop, liquid holdup, gas−liquid interfacial area and mass-transfer coefficient, catalyst wetting efficiency, catalyst dilution with inert fines, and evaluation of trickle-bed models for liquid-limited and gas-limited reactions. The effects of high-pressure operation, which is of industrial relevance, on the physicochemical and fluid dynamic parameters are discussed. Empirical and theoretical models developed to account for the effect of high pressure on the various parameters and phenomena pertinent to the topics discussed are briefly described.
